Dan Carpenter f6d44b1aa4 fs/ntfs3: Prevent integer overflow in hdr_first_de() ...

[ Upstream commit 6bb81b94f7a9cba6bde9a905cef52a65317a8b04 ]

The "de_off" and "used" variables come from the disk so they both need to
check.  The problem is that on 32bit systems if they're both greater than
UINT_MAX - 16 then the check does work as intended because of an integer
overflow.
